People suffering from diabetes-related nerve damage often experience difficulty swallowing, which can make it difficult to take medications on time and maintain a healthy diet. In a study of diabetic neuropathy sufferers, researchers at Spain's Garibaldi Hospital said that Botox injections may be the key to alleviating swallowing difficulties. The small-scale experimental study was based on a trial of a dozen diabetic patients, all of whom received injections of Botox into the esophagus. In 10 of the 12 patients, a single injection completely cleared up the problem for 12 weeks. All patients experienced renewed difficulty swallowing 24 weeks after the injection. However, follow-up treatment was found to be equally effective.
